After a two year engagement, Nicollette Sheridan and Michael Bolton have ended their relationship. They’ll be back together again.

John Mayer and Jennifer Aniston have ended their non-serious relationship. A friend close to John said:

"There’s been a bit of tension for some time. They initially opted for a break, hoping a trial split might make them stronger. Sadly it doesn’t seem to have worked."

"John took the decision to end things as he felt he just wasn’t ready for the level of commitment that Jennifer deserved."

"Contrary to reports, Jen didn’t want to have kids or marry this year, but she did want to set a timetable for their future together."

"She also wanted him to assure her he would cut down his tours in the future when they did eventually have children."

"Initially, Jennifer was furious when he told her of his decision but now she’s simply sad – not to mention a little heartbroken."

"They have spoken on the phone since the split and are trying to remain on good terms."

"But unless John has a dramatic change of heart, it’s unlikely they’ll rekindle their romance."

The New York Daily News reports Aniston is already dating someone else, and he’s a model in Los Angeles. Aniston doesn’t have serious relationships anymore. She’s still longing for someone like Brad Pitt to come along again.

Adrian Grenier and Isabel Lucas three weeks ago, right after the accident that left Shia LaBeouf with a crushed hand. A source said:

"It wasn’t working out. Adrian saw her with Shia and that was kind of it, the crash, their hanging out. He obviously didn’t appreciate it."

Lucas was going home with Shia the night of the accident, even though she was dating Adrian. She’s a cheater. Only yesterday we saw Lucas with Shia again.

Kate Hudson and Lance Armstrong are no longer a couple. Just when they started doing things together, even with their kids involved, they decided to break off their dating relationship.

After five years of dating, Jimmy Kimmel and Sarah Silverman have ended their relationship. Reps for both confirmed the split.
